5 rulings from Wizards of the Coast
- 25 August 2015If you return an Aura to the battlefield this way, you choose what it will enchant as it enters the battlefield. This doesn't target any player or permanent, so you could attach an Aura to a permanent with hexproof controlled by an opponent, for example. If there's nothing the Aura can legally enchant, it stays in the graveyard.
- 25 August 2015A "nonland permanent card" is an artifact, creature, enchantment, or planeswalker card.
- 8 November 2024A landfall ability doesn't trigger if a permanent already on the battlefield becomes a land.
- 8 November 2024A landfall ability triggers whenever a land you control enters for any reason. It triggers whenever you play a land, as well as whenever a spell or ability puts a land onto the battlefield under your control.
- 8 November 2024Whenever a land you control enters, each landfall ability of the permanents you control will trigger. You can put them on the stack in any order. The last ability you put on the stack will be the first one to resolve (As a result, you can have those abilities resolve in the order of your choosing.).
